I was at the dealership 2 weeks ago to talk to my salesman about ordering a new 4.8 loaded and when we got to the part of the deal about taking my trade in this is where it got ugly. I own a 2003 4.6 with 55k on it fully loaded with rear dvd system and its CPO in beautiful condition with a KBB trade in value of 35k in good condition, and they told me the most they could give me is 28k, while taking only 2% off the new X5. This would be the third bmw I bought from this dealer and salesman, the first two were leases so I never had to trade anything. Has anybody else experienced this type of difference in what KBB says and what the dealer will offer ?
